Dear Welcome to HCM We understand your concerns I went through your details. For your information, trichotillomania is scratching scalp and pricking hair thereby the hair strands get strangled and come out in bunches. Due to this activity, hair fall is also common. Eating hair or hair follicles may not come under the category of trichotillomania but it could be included in the behavior therapy for trichotillomania. The eating behavior is bizzarre and therefore, need to analyze the patients behavior and cognition. In these cases, a panel of dermatologist, psychologist and psychiatrist will be able to provide you a good remedial measure.
